Agility Fuel Solutions has announced the availability and ongoing development of large-capacity ProCab H hydrogen storage systems for trucks.

The ProCab H hydrogen storage systems are lightweight, compact, self-contained modules that mount behind the cab of Class 8 trucks. The system designs are based on Agility’s ProCab behind-the-cab CNG fuel system architecture, which has been track tested for a simulated 1 million miles and validated by OEM test programmes. The ProCab H family is the product of multiple design iterations, including hydrogen storage systems recently used on zero-emission hydrogen trucks made by US Hybrid and Kenworth.

ProCab H systems include 350 bar composite cylinders with fuel capacities of 23.5, 28.2 or 33.9 kg of hydrogen, require only 31 inches of rail space behind the truck cab, and are available in custom colours to match fleet livery. All systems have fuel management and pressure control equipment needed for fuelling and defuelling the vehicle and delivering hydrogen at a specified pressure to the fuel cell.

Agility also plans to introduce next-generation hydrogen storage systems based on large-diameter Type 4 composite cylinders with 700 bar service pressure being developed in partnership with Hexagon Composites. These higher-pressure, higher-capacity hydrogen storage systems will enable longer driving ranges and could be used in regional haul Class 8 trucking applications such as Toyota’s Project Portal.

“Agility has made integrated hydrogen fuel storage systems for trucks and buses since 2002,” says Jeff Scott, Agility’s Co-founder and VP, Sales. “We’ve recently seen increased interest in hydrogen technology, and we realised that high-quality manufactured on-board hydrogen storage would be key to making hydrogen trucks scalable in the marketplace. We are pleased to offer our ProCab H product line and look forward to working with our OEM customers to help bring zero-emission hydrogen trucks to market.”

The Institute for Advanced Composites Manufacturing Innovation (IACMI) has announced the Phase I completion of a project led by DuPont, partnering with Fibrtec and Purdue University, focused on the creation of a new carbon fibre composite manufacturing process that exhibits improved fabric formability characteristics compared to traditional woven materials.

Powertrains, be they conventional, hybrid or fully electric, will need to be light in weight if carmakers are to meet the stringent regulations on carbon dioxide emissions (CO2) to come into force in 2025 – and composites will be key to making this happen. This was the message highlighted at the Lightweight Composite Solutions Conference organised by Vyncolit and Sumitomo Bakelite Co Ltd and held in Gent, Belgium.
